COAL-CAR.

SPECIFICATION forming part of Letters Patent No. 305,189, dated September 16, 1884.

Application inea December 26, Issa (No model.)

To all whom t may concern:

Be it known that I, DAVID Horr, of West Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Coal-Cars, of which the following is a specification.

This invention relates to improvements on the coal-car for which Letters Patent of the United States No. 27 2,550 were granted to me on the 20th day of February, 1883; and the objects of my present improvements are to simplify the construction of said car, to increase the capacity thereof, to lower the cen.

ter of gravity of its superimposed load, and to bring the discharge-openings more closely to the level of the tracks of the railroad. These objects I attain by means of the construction illustrated in the accompanying drawings7 which form part of this specification, and in which- Figure l is a combined side elevation and longitudinal section of an eight-wheel car containing my improvements; Fig. 2, aplan view of the same, and Fig. 3 a transverse section at the line X X of Fig. 1.

As represented in the drawings, A is the frame-work of the car, on which the box B, for containing the coal, is erected. Said box is preferably made in a rectangular form, with vertical sides, and havingat each end inclined planes b,which reach nearly to the top of said boX, and, sloping downward, terminate at opposite ends ofthe discharge-opening. At each side of said bor. inclined planes b are formed, as shown in Fig. 3. The object of the inclined planes b and b is to direct the discharge of the coal toward and through the dischargeopenings, all of which are formed longitudinallyinV the bottom of the car.

C is a longitudinal partition formed in the lower part of coal-receptacle, on the center line thereof.

D represents trap-doors for closing the discharge-openings inthe bottom of the car. SaidV doors are arranged in a s eries of four pairs of leaves, that are parted longitudinally, two pairs being arranged in front of the transverse center line of the car, and the other two pairs being placed at the rear of said line. rIhe inner leaves of the doors D are hinged, as at d,

to the bottom edge of the partition C, and the outer leaves are hinged, as at d', to the lower edges ofthe pieces that form the inclined I planes b. By making the doors D to separate longitudinally I am enabled to have their leaves so narrow that the coal-box can be carried down nearly to the plane of the axles of the truck-wheels, much closer to the level of the tracks than has ever heretofore been accomplished, and, as a consequence, the center of gravity of the load is correspondingly lowere E represents transverse shafts arranged across the box B in such manner that one of said shafts will lie directly over two pairs of the doors D. Chains e, each having one of its ends made fast to and adapted to wind around its appropriate shaft, have bifurcated ends, which are attached to the doors D, and are so arranged that when the shafts E are rotated in one direction the chains will be wound around them, and thereby the doors D will be swung upward into the `horizontal positions shown in Fig. 3,' to close the dischargeopenings to which they are respectively applied. When the doors D are closed, the shafts E are prevented from rotating, to permit the unwinding of the chains, by means of the ratchet-wheels c', (secured to said shafts) pawls c2, and keepers e3, as fully described and set forth in my Letters Patent `No. 272,550, above referred to.

To dump the load contained in the'boX B, the ratchet-wheels e are released from the control of the pawls et, and then the weight of the load resting upon the doors D will force the latter to swing downward into the positions indicated by the dotted lines in Fig. 3, so as to permit the load in the box B to fall through the discharge-openings in the bottom of the car. The shafts E have their bearings in the 4hangers F, which are secured to the transverse beams G. Said beams are arranged in line with and directly over the shafts E, thereby affording the required support therefor, and also `forming guards for said shafts, to protect them and their chains c from being injured by the falling coal while the car is being loaded.

I claim as my invention- 1. In a coal-car, the combination ,with a box,

IOO

B, provided with longitudinal discharge-openings, andwith end inelines,b,and sideinelines, b-, all of said inclines being carried down to -the lowest plane of said discharge-openings,as herein shown and described, the said box being also provided with a longitudinal partition, C, for dividing the said discharge-openings into two separate series, of the trap-doors D, hinged to the side inclines, b', and central partition, C, and arranged to swing longitudi nally in respect to the box B from a plane that lies nearly at alevel with the plane of the axes of the truck-wheels, as and for the purpose herein speciied.

2. In a coal-car,the co1nbination,with a box, I 5

B, provided with the inclines b and b', and trapdoors D, arranged on aplane that lies entirely below the under side of the frame-work A of the ear, asherein set forth, of the shaftsE and chains e, adapted to operate the doors D, as 2o herein described,and the transverse beams G, fixed above the shafts E, as and for the purposes herein specified.
